RESEARCH PRODUCT

Elimination of spurious kinematic modes in hybrid equilibrium elements

subject

Settore ICAR/08 - Scienza Delle Costruzioni Hybrid Equilibrium SKM Mixed Dual Analysis

description

Hybrid stress elements are proposed as alternative to standard finite elements for linear and non linear analysis. Hybrid stress formulation is developed in a rigorous mathematical setting and an original approach for elimination of spurious kinematic modes is presented. Hybrid equilibrium method is compared to classical displacement based method by linear elastic analysis of some well known structural examples.
